Varicoceles: postoperative prevalence--a prospective study with color Doppler US

OA Cvitanic, JJ Cronan, M Sigman and ST Landau
Department of Diagnostic Imaging, Rhode Island Hospital, Providence 02903.

To define the ultrasound (US) prevalence of varicoceles after surgical repair, 28 postoperative patients underwent color Doppler US. A group of 26 control subjects also underwent color Doppler US to establish the prevalence of varicoceles in the healthy population. Eighteen of 28 (64%) patients who underwent color Doppler US scanning 16.4 months, on average, after varicocele repair had evidence of a varicocele, a number similar to that reported in other series for infertile men before surgery. Dominant veins in the postoperative patients were larger (P < .01) than those in the control subjects. Postoperative improvements in sperm parameters and conception rate in our subjects were 58% and 43%, respectively, consistent with findings reported in the literature. The prevalence of varicoceles detected at color Doppler US in our healthy population was 42% (11 of 26). Physical examination after surgery failed to show a varicocele in 20 of 22 (91%) patients examined. The discrepancy between sperm parameters and the results of color Doppler US and physical examination raises questions about the utility of US as a means of evaluation in the postvaricocelectomy patient.
